Current Attempt in Progress

Block $A,$ with a mass of $4\mathrm{.}0$ kg $,$ is moving with a speed of $2\mathrm{.}0\frac{m}{s}$ while block $B,$ with a mass of $8\mathrm{.}0$ kg $,$ is moving in the opposite direction with a speed of $3\mathrm{.}0\frac{m}{s}.$ The momentum of the center of mass of the two$-$block system is:

$12kg*\frac{m}{s}$ in the same direction as B

$16kg*\frac{m}{s}$ in the same direction as A

$60kg*\frac{m}{s}$ in the same direction as A

$32kg*\frac{m}{s}$ in the same direction as $A$

$16kg*\frac{m}{s}$ in the same direction as $B$
